 * 
 *      Current gen Browsers
 *       
 *      FF3         array.join is ~2x faster
 *      Safari 3    array.join ~1.5x faster
 *      Opera 9     += ~3x faster
 *      ie6     array.join ~6x faster
 *      ie7     array.join ~4x faster
 *      
 *      Next gen browsers
 *      
 *      FF3.1       += array.join equal in speed
 *      Chrome      +=  ~1.25x faster
 *      IE8     array.join ~1.6x faster
 *      Webkit      array.join ~2x faster
